I've got a newly established fescue lawn here in North Carolina. No shade and hot weather lately. I've been mowing the fescue on the max height 5.5 so not to let the heat completely kill it. This is a brand new 915E btw. So it seems that it clogs up quite easily and throws out chunks of matted grass but it also tends to leave a small strip of grass that is incompletely cut no matter have slow or fast I mow. It seems A LOT of grass is getting stuck to the underside of the deck......This could be the culprit restricting air flow. Is there a solution? High vacuum blades? Some way to keep grass from getting stuck to underside? Any help appreciated because I didnt expect this from a $8k mower.
